" on the spindle, or the spindle was raised and lowered in the cord drive casing. 'In any in stance the cop or the spindle changed its position with relation to its bearingor support wherefrom a non-uniform running of the cop My present invention does away with this drawback. It consists in its broader aspect in that the spindles which are positively actuated by worm gear mechanisms aremovcd up and down with their actuating gears for theformation of the cops. This results in the advantage that the spindles are always in the same position with relation to their drive, so that the cops or spindles are always running uniformly and an unobjectionable yarn or cord is produced. x In the drawing which illustrates apreferred embodiment of my invention:

The machine lllustrated in the drawing as embodying my. present invention belongs to the type of spinning machinery at which the spindles are positively operated by worm by my U. S. Patent No. 1,526,709.

As shown in the drawing this machine comprises the main bearing shield 1 and the standards 2 between which the spindle beam 3, the ring rail 4., the cord guiding beam 5 and the feeding and stretching mechanism are arranged. The spindle beam 3 is carrying the worm gear driven spindles? which ring rail 4 according. to the growth of the cops, as will be readily understood by those skilled in this art.

' The spindles 12 are rotatably carried in a beam 13 extending between themain bearing shield 1 andthe standards 2 and are connected with worm gears 14 meshing with worms 15 support on both sides of the worms 15 in bearings 17. I

The spindle beam 3 is provided with arms 18 each of Which is rotatably carrying a nut 19 having a threaded engagement with the spindles 12, as shown, and being provided with worm gears 20 which mesh with worms 21 secured to a shaft 22. The shaft 22 is supported by bearings23 and extends past the whole width of the machine. By the worms 21 engaging with the worm gears 20 thenuts 19 are normally locked against rotation. If therefore the spindles 12 are rotated they impart a lifting or lowering movement, as the case may be, to the spindle beam 3 by means of the nuts 19. By rotating also the nuts 19 an additional movement may be impartedtothe beam3.

In order that thespindle beam 3 in its totality may perform its liftingand lowering movement, I arrange, in accordance with one of the main features of this present inven; tion, a special connection of its shaft 8 with the main actuating gear 24; of the machine. To this end the shaft 8 is provided with a worm gear 25 meshing with a long, vertical- 1y extending worm 26 carried by bearings 27 of the main bearing shield 1 of the machine. At the side opposite to worm gear 25 the worm 26 meshes with the main actuating gear 24 driven by a pinion 28 from the of a lengthwise extending shaft 16, having non-illustrated motor. The extended worm 26 permits a vertical movement of the spindle beam 3 without disengaging gears 25 and 26.

In accordance with the usual practice of this type of machines the stretch and feed mechanism is actuated from the main gear 24, for example by means of an adjustable sprocket chain drive the shaft of the main gear actuating a sprocket wheel 29, which drives a sprocket wheel 31 by means of a chain 30, sprocket wheel 31 being connected with a pinion 32 which meshes with an interchangeable pinion 33 actuating the stretch and feed mechanism.

The lifting and lowering movement of the spindle beam is'preferably governed by the drive of the stretch and feed mechanism. To this end the main shaft 34 thereof which is actuated by pinion 33 is carrying a bevel gear 35 meshing with the bevel gear 36 of a vertical shaft 37 which at its upper end is supported in a bearing 38. The low-er'end of shaft 37 is loosely carrying two bevel gears 39 and 40 supported by bearings 41 and 42 respectively and engaging with a bevel gear 43 fixed to the shaft 16. Upon shaft 37 I arrange a coupling member adapted to rotate with the shaft and to be lengthwise shifted thereon and having jaws ,o-r cones adapted to be engaged with corresponding jaws or cones of the gears 39 and 40-respectively so as to establish a positive drive between shafts 16 and 37 in the one or-the other direction and efiect the lifting or lowering of beam 3, as will be readily unde'rstood.

The movement of the coupling elements so far described is preferably controlled by the drive of the bevel gears 39 and 40. To this end.- theshaft 37 is provided with a worm 45 meshing witha worm gear 47 having nearly straight teeth and being carried by a stub shaft 46. The worm gear 47 is carrying an exchangeable cam disk 48 the cam 49 of which is acting onrollers 50 of a guide member 52 sliding in guides 51. The cam 49 is thus lifting and lowering the guide .oted to a lever 63.

member 52 in accordance with the particular number of revolutions of'shaft 37, it being besides connected by a rod 53 with a lever 54 controlling the clutch element 44 by means of a pin 55.

Since also the additional vertical movement of the spindle beam 3 must be controlled by the machine, I further provide a pinion 56 meshing with gear 47 but having only half the number of teeth thereof. The pinion 56'is revolvingvon a stubshaft 57 of the main bearing shield 1 and carries an eXcentric pin 58 projecting into the longitudinal slot 59 of a lever'61 journalled at 60 at its upper end and being pivoted at its lower end to an arm 62, the other end of which is piv- The lever 63 is pivoted to the shaft 22 which'moves upward-1y and downwardly with the spindle beam and carries a feed pawl 64 cooperating with a ratchet 65 mounted on the shaft 22. At each- 1. In a spinning machine, a ring rail, a

spindle beam mounted for movement toward and from the ring rail, spindles rotatably mounted on the spindle beam, a shaft for imparting motion to the. spindles and movable with the spindle beam, a drive shaft, gearing interposed between the drive shaft and thespindle rotating shaft for rotating the last mentioned shaft, and means ac tuated by an element of the gearing for imparting movement to the spindle beam in synchronism with the formation of the cops on the spindles.
